In addition to the beep codes, your computer also displays error messages to inform you if there is a problem, be it a hardware or software issue. A majority of software-related issues occur due to malware infection and a damaged Windows registry. The good news is that with the right software you can easily prevent errors from occurring due to these two reasons.

To prevent errors from occurring due to malware infection, install reliable protective suites, such as STOPzilla Antivirus and Spyware Cease on your computer. You can avoid errors occurring due to registry related issues by maintaining a clean and healthy registry. To achieve this, regularly clean your Windows registry using an advanced registry cleaning tool, such as RegServe.
